LUBRIGATOR.

Specification of Letters Patent.

Patented May 9, 1911.

Application filed July 8, 1909. Serial No. 506,591.

To all whom it may concern:

Be it known that I, CHRISTIAN \VILLIAMS, a citizen of the United States,residing at- Wittenberg, in the county of Shawano and State ofWVisconsin, have invented a new and useful Lubricator; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

The invention about to be set forth pertains to a new and usefullubricating device or means for wheels and similar devices, especiallywagon wheels; the invention aims as its essential object to provide animproved device of this design, which is simple and efficient inconstruction and durable, as will be readily observed.

The invention aims as a further object to provide means wherebylubricants may be applied to the spindle of an axle without removing thewheel therefrom, and further to provide means by which the oil gutter orgroove of the spindle of the axle is closed at its end, so as to holdthe lubricant in said gutter or groove.

Another object of the invention is to provide means disposed radially ofthe hub of the wheel, for the reception of a screw bolt, which may beremoved for the insertion of lubricant.

To obtain a full and correct understanding of the details ofconstruction, combi nations of features, elements and advan tages,reference is to be had to the hereinafter set forth description andaccompanying drawings in connection therewith, wherein- Figure 1 is asectional view through the hub of a wheel, showing the same mounted upona spindle of an axle. Fig. 2 is a sectional view upon line 22 of Fig. 1.Fig. 3 is a face view of the wheel, showing the means for retaining thesame upon the spindle.

In regard to the annexed drawings, 1 designates an axle of a vehicle,which is provided with the usual spindle 2. This spindle is providedwith a single oil gutter 3, for the purpose of containing suitablelubricant.

Mounted upon the spindle 2 is the usual wheel 3, having the ordinary hub4:. This hub is provided with an inner casing -5, which is designed toengage the spindle. Extending through the hub radially is a casing 6,which is substantially rectangular in section, and is provided with aflanged portion 7 having apertures 8, through which suitable screws 9extend. These screws penetrate sufiiciently so as to thoroughly engagethe hub of the wheel, in order to prevent displacement of the casing 6.The casing 6 is long enough in order to extend into an aperture 5 of thecasing 5, so as to prevent rotary displacement of said casing 5. Thiseasing 6 is provided with a hollow threaded inner surface 9, for thereception of the screw bolt 10, which may be removed when desired forthe insertion of lubricant, as shown clearly in Fig. 1 of the drawings.

The spindle 2 is provided with an extended restricted threaded portion11. A nut 15 is threaded to the portion 11 and is provided with asuitable flange 13, to engage the hub of the wheel, in order to hold thewheel in place and at the same time prevent the escape of the oil.

From the foregoing, the essential features, elements and the operationof the device, together with the simplicity, thereof will be clearlyapparent.

The flange 7 of the casing 6 is seated within a recess 17 of the hub,and the periphery of the said flange is slightly beveled, as shown at18, in order to fit the recess snugly.

Having thus fully described the invention, what is claimed as new anduseful is A lubricating device comprising in combination with an axlehaving a groove therein, a wheel, a hub, a receptacle sunk in said hubfor a lubricant and having its external surface of angular form toprevent rotation, said receptacle having its lower end concaved, anintegral flange at the upper end of said receptacle, having screw-holestherename to this specification in the presence of in, screws adapted topass through the screwtwo subscribing witnesses. holes to enter said hubscrew threads on the interior of said receptacle a pusher mount-CHRISTIAN WILLIAMS 5 ed therein, complemental threads on said Witnesses:pusher,vand a square head on said pusher.
